IMPROVEMENT IN GAUGES FOR SETTING CARRIAGE-AXLES.

Specilication forming part of Letters Patent No. 126,995, dated May 21,1872.

To all whom t may concern: A

Be it known that I, LEVI TAYLOR, of Marlborough, in the county ofMiddlesex and State of Massachusetts, have invented an Improved Gaugefor Setting Carriage-Axles, of which the following is a full, clear, andexact description, reference being had to the accompa-nying drawingmaking part of this specification, in whichs Figure l is a perspectiveview of my improved gauge. Fig. 2 is a longitudinal section through thecenter of the same, with a carriage-axle applied thereto; Fig. 3,detail, to be referred to.

My invention consists in an implement composed of a bar having astationary rest and a movable rest, in combination with a slidingspring-gauge, provided with a scale and index, to be used in settingcarriage-axles, whereby the inclination of the journals may beaccurately determined and made to correspond `exactly with each other.

To enable others skilled in the art to understand and use my invention,I will proceed to describe the manner in which I have carried it out.

In the said drawing, A is a rectangular bar, from one end of which risesa stationary standard or rest, a. b is a movable standard or rest, thebottom of which is secured to one end of a smaller rectangular bar, B,provided with a metallic loop, c', made to slide upon the bar A, andclamped in any desired position thereon by means of a setserew, c',which vpresses against a notched block, d, placed between the bottom ofthe loop c and the bar A. e is a movable plate, the lower end of i whichis provided with a rectangular loop, j',

which fits over and slides upon the bar B, a spring, g, at the bottom ofthe loop producing sufficient friction to retain it in the desiredposit-ion when adjusted. From the back of this plate e project twohorizontal lugs, h t', Fig. 3, one, h, at its top, and the other,t', ashort distance above the loop j'. Through holes in these lugs passes thevertical portion k of the gauge Z, which is provided u ith an index orpointer, m, which passes through a slot, u, in the plate e, to itspoint, which is provided with a graduated scale, o. p 'is a stop,between which and the lower lug fi, and surrounding the vertical portionk of the gauge, is placed a spiral spring, r, the resistance of whichpresses the top of the gauge l upward.

When the journals of the axle (preferably tapered) are to be set at thenecessary inclination downward to give the wheels the desired .pitch,the stationary rest a is brought snugly up under one oi' the shoulders 5of the axle O, and the movable rest b is slid along the bar A under theother shoulder 5. The slidmg gauge Z is now moved along the bar B up tothe part oi one end of the journal where the wheel is to run, when thegauge is depressed, and is brought thereunder against the resistance ofthe springr, and the position oi' the index is carefully noted. Thejournalat this end ofthe axle is now deflected on the anvil, and thenplaced on the gauge to ascertain if it has been sufficiently inclined.If it is required to be inclined still further, the operation isrepeated until the journal, when placed upon the gauge, brings the indexdown to a predetermined point. The other journal is then deflected in asimilar manner, so that, when placed upon the gauge, it will carry theindex down to the same predetermined point of the scale to which it wascarried by the first journal; and it will thus be seen that, by the useof my improved gauge, both journals of an axle can be deiiected orinclined exactly alike, to give the required pitch to the wheels to beplaced thereon. By giving the laxle a quarter turn, the index will showif the journal h as been accidentally bent to one side oi a verticalplane passing through the center of the axle while giving it the desiredpitch 5 and 1f such is the case, the journal is straightened on ananvil, and when perfectly true the index will be carried down to thesame point when the opposite sides of the journal are applied thereto.

If preferred, the bar B may be dispensed with, in which ease the plate emust be prolwoudeg.L with a loop adapted to slide upon the O HIMSELFClaim. Witness my hand this 9th day of April, A. What I claim as myinvention, and desire- D' 1872' to secure by Letters Iatent, is- LEVITAYLOR.
